GAS-PURIFIER.

SPECIFICATION forming part of Letters Patent N0. 632,399, datedSeptember 5, 1899.

Application filed March 25 1899.

T0 all whom it may concern:

Be it known that I, BYRON E. CHOLLAR, a citizen of the United States,residing at the city of St. Louis, in the State of Missouri, haveinvented certain new and useful Improvements in Gas-Purifiers, of whichthe following is a full, clear, and exact description, reference beinghad to the accompanying drawings, forming part of this specification.

My present invention relates to a gas-purifier of the type set forth inapplication for patent filed by me August 5, 1898, under Serial N o.687,773, the object of the present improvement being to supplyboxes atthe inlet or outlet openings of the purifier-tanks, above said openings,so that in the event of the purifying material settling within the tankthe said box will afford opportunity for ingress or egress of the gas toor from the passage-way between the layers of purifying material insteadof the inlet or outlet opening becoming closed by the purifying materialsettling thereto.

My invention consists in the application of the said box as stated andits form of construction, as will hereinafter be fully described, andpointed out in the claim.

Figure I is a top view of a pair of purifiertanks connected by reversepiping, one of said tanks being shown partly broken away in horizontalsection to show the interior construction. Fig. II is an enlargedvertical sectional view of one of the tanks, taken on a line through thegas inlet or outlet. Fig. III is a perspective view of the boxconstituting my improvement.

The purifying-tanks l and la and the reverse piping 2 that connects themare all substantially the same ein construction as those shown anddescribed in my application for patent hereinbefore referred to. Asstated in said application, the piping 2 is connected to both of saidtanks in such manner that the iow of gas therethrough may be caused to`serial No. 710,445. (No model.)

referred to, the inlets or outlets of the said tanks may either of thembe used as an outlet or an inlet. For the purpose of convenience indescription I will, however, refer to one of the openings as an inletand the other as an outlet, and in Fig. II, 3 designates the inlet,while 4. designates an outlet tube, both said inlet and outlet tubesbeing provided with communication to the piping 2.

5 ,designates the lower layer of gridwork, on which the lower layer 6 ofpurifying material is supported.

7 designates the double gridwork, having a gas passage-way 8 therein,and 9 is the upper layer of purifying material, lnounted on the doublegridwork 7.

The layers of purifying material 6 and 9 being wholly supported by thegridwork, as provided for in the application for patent referred to, itis evident that the said layers of purifying material and doublegridwork interposed between them are susceptible to settling in thepurifier-tank, in which event the gas passage-way 8 within the doublegridwork 7 would be removed from the pipe-communicating opening 3, andtherefore the free ow of gas into or out of the purifier through saidopening might be interfered with. To overcome this difficulty, I haveprovided a box 10, adapted to fit loosely against the tank-wall andmounted on the double gridwork immediately above the opening 3. This boxis shown in detail in Fig. III and `is composed of side walls 11 and atapering wall 12, and is open at its point of contact with the tank-walland at its bottom. With the use of this box the purifying material isupheld away from the opening 3, and as the purifying material settlesthe said box descends into registration with the opening 3, and receivesthe flow of the gas in its passage into the purifier or therefrom,according to the direction of its flow, and thereby avoids any cloggingof the opening 3.

I claim as my invention- In a gas-purifier, the combination of a tank, alower gridwork located therein, a lower layer of purifying materialmounted on said gridwork, a double gridwork on said lower layer ofpurifying material, provided with a gas l passage-way extendinglaterally therethrough, said tank being provided with an inlet or outletlocated in proximity to the passage-Way in said double gridwork, anupper layer of purifying material mounted on said double gridwork andWholly supported thereby, and a box having an open side and open at itsbottom, mounted on said double gridwork in proximity to said inlet oroutlet, adapted to register with said inlet or outlet on the settling ofthe said layers of purifying material and the double gridwork interposed1o between them.

BYRON E. CHOLLAR.
